Diego Maradona claims Manchester City could blow the title because Roberto Mancini is "too defensive".

Maradona feels Mancini has become too negative recently after making a flying start to the campaign with City.

The Blues banged in 39 goals in their first 11 league games to take 31 points from a possible 33.

But they have managed just 16 goals in their last 11 matches, dropping 11 points.

Maradona, who has been in Manchester this weekend visiting his son-in-law Sergio Aguero and his family, says Manchester United could beat City in the title race because Mancini is not bold enough.

"My heart says Manchester City, but I believe Mancini with all the players he's got, is not daring enough," said the Argentine legend.

"He's a bit too defensive. Maybe because he is Italian."

Maradona feels United are more attacking and said: "As an organisation, and with their style of play, I think United are more aggressive. But if I have to support one team, I'll be a fan for my son-in-law."

Maradona wishes Aguero were still at Atletico Madrid, but feels he made a great move in joining City last summer.

"I think today, watching from my home in Dubai, seeing Aguero in Madrid would make for much more interesting matches than Kun Aguero at Manchester City," said the Al Wasl coach.

"I talked to the president of Atletico Madrid and I told him that Aguero had amazing potential, and that he should surround him with good players so that Atletico could make history with him.

"As you know he did not listen to me. He didn't listen. He sold Kun and I, as his father-in-law, think he chose well. He has finally found a place in the world and a team where he can fight for important things."
